[Bug fortran/28788] [gfortran: 4.1, 4.2 regression] ICE on valid code

2006-08-26 Thread paulthomas2 at wanadoo dot fr


--- Comment #12 from paulthomas2 at wanadoo dot fr  2006-08-26 09:30 ---
Subject: Re:  [gfortran: 4.1, 4.2 regression] ICE on valid
 code

Jerry and Martin,

All of this is very depressing - I can reproduce the 32 bit version of 
the problem and, I suppose, will reproduce the 64 bit version in a 
moment.  There are three things that really start me scratching my head:

(i) gcc-4.2 has it that there is a format error in the module file itself:
[EMAIL PROTECTED] f90bug]# /svn-4.2/bin/gfortran -I./*.mod -c lensing.f90
Fatal Error: Reading module modelparams at line 27 column 73: Expected 
integer;
(ii) This difficulty disappears if I use 4.1; and
(iii) I cannot for the life of me understand what the -I. would do to 
affect the parsing and processing of the .mod file. (Jerry, is there any 
recent IO library modification that would do this?)

Still worse and what has me completely floored is this

module z
  type :: x
integer :: i
  end type x
end module z

module modeldata
  use z
  type :: cltransferdata
type(x) :: ls
integer :: numsources
integer :: num_q_int
real(8) :: q_int
real(8) :: dq_int
real(8) :: delta_p_l_k
  end type cltransferdata
end module modeldata

Produces a modeldata.mod like this:

GFORTRAN module created from tests.f90 on Sat Aug 26 10:43:24 2006
If you edit this, you'll get what you deserve.

UNKNOWN) (UNKNOWN 0 ()) 0 0 () () 0 () ())
)

('modeldata' 0 12 'cltransferdata' 0 2 'z' 0 11 'x' 0 4)

Note the entry starting with (2 'cltransferdata'... ; this has a 
reference to the component 'ls' on the next line. (3 'ls' (DERIVED 4 ()) 
says that 'ls' is derived and is of a type that is defined in entry 4.  
This entry is:

4 'x' 'z' 1 ((DERIVED UNKNOWN-INTENT UNKNOWN-PROC UNKNOWN) (UNKNOWN 0 ())
0 0 () () 0 ((10 'i' (INTEGER 4 ()) () 0 0 0 ())) PUBLIC ())

which says that it is declared in module z, is derived and has an 
integer component i.

with the -I. option, like you, I get

  use ModelData
  1
Error: The component 'ls' is a PRIVATE type and cannot be a component of 
'cltransferdata', which is PUBLIC at (1)

(Why is it this USE statement and not others, either before or after?)

Anyway, ignoring this last question for the time being, I find in 
modeldata.mod the entry(line 55)

24 'cltransferdata' 'modeldata' 1 ((DERIVED UNKNOWN-INTENT UNKNOWN-PROC
UNKNOWN) (UNKNOWN 0 ()) 0 0 () () 0 ((25 'ls' (DERIVED 26 ()) () 0 0 ())
(27 'numsources' (INTEGER 4 ()) () 0 0 ()) (28 'num_q_int' (INTEGER 4 ())
() 0 0 ()) (29 'q_int' (REAL 8 ()) (1 DEFERRED () ()) 1 1 ()) (30 'dq_int'
(REAL 8 ()) (1 DEFERRED () ()) 1 1 ()) (31 'delta_p_l_k' (REAL 8 ()) (3
DEFERRED () () () () () ()) 1 1 ())) PUBLIC ())

You will see that 'ls' is of derived type declared in entry 26, which is 
present in the file but out of order.  That said, it does not matter 
where I put it, nor is it PRIVATE.

PRIVATE objects do not appear at all in .mod files.

I will think some more about this but I will, at the same time, prepare 
the patch to revert to the original state, with the kludged up version, 
in resolve.c, of the fixes for the PRs.  The release of 4.2.0 is 
looming!  This is such a pity because the current version of derived 
type association is so much better in principle.

Paul

I'm getting an ICE and segmentation fault in the following code. I think it may
be related to Paul Thomas's observation about pointers to components of derived
type arrays. However, it does compile under these circumstances:

* when foo and bar are not in the module
* when the module contains foo or bar but not both
* when the types a and b have no reference to each other
* when  ", only, a (or b)" is not used on the use statement

  MODULE type_mod
 TYPE a
   INTEGER  :: n(10)
 END TYPE a
!
 TYPE b
   TYPE (a), POINTER :: m(:) => NULL ()
 END TYPE b
  END MODULE type_mod


  MODULE seg_mod
  CONTAINS
  SUBROUTINE foo (x)
  USE type_mod, ONLY : a ! fails
!  USE type_mod  ! works

A related testcase is:

 Which should be optimized into --

We do have code to notice use-before-specialization errors.  For example:

  template  void f();
  void g() {
f();
  }
  template <> void f() {}

results in an error.

However, the code to initialize static variables is not generated until
end-of-file, so we do not realize that we are in this situation.  (See
expand_static_init for the point at which we defer initialization.)

[Bug tree-optimization/28839] [4.2 Regression] ICE in tree-vectorizer.c with -O2 -ftree-vectorize -funswitch-loops

2006-08-26 Thread rguenth at gcc dot gnu dot org


--- Comment #4 from rguenth at gcc dot gnu dot org  2006-08-26 18:06 ---
Also fails on i686 with -O2 -msse2 -mfpmath=sse -ftree-vectorize
-funswitch-loops
and is a bug in unswitching which creates

:
  if (t1_7 != 0) goto ; else goto ;

:;

  # ready_20 = PHI ;
  # i_1 = PHI <0(3), i_17(5)>;
  # ready_2 = PHI ;
:;
  #   ready_12 = V_MAY_DEF ;
  ready[i_1] = 0;

note ready_20 and ready_2 which are both life on entry to block L15 which
is invalid for virtual operands.  Updating of the SSA form is broken here.
Slightly smaller testcase:

tatic int ready[10];
void test_once (int t1)
{
  int i;
  for (i = 0; i < 10; i++)
{
  ready[i] = 0;
  if (t1)
if (f())
  return;
}
  abort ();
}

OK, so that's where you got your symbols, but where did you get your list of
demangled strings?  Did you just compare directly to the source code?  Or are
you using some other demangler?

[Bug middle-end/28727] Wrong code generated (assignment incorrectly optimized out)

2006-08-26 Thread qrczak at knm dot org dot pl


--- Comment #3 from qrczak at knm dot org dot pl  2006-08-26 19:15 ---
The problem seems to be caused by illegal type punning. Rewriting the code to
avoid pointer casts cures the bug, and -fno-strict-aliasing cures it too, so
gcc is probably correct.

Thanks to Michael Veksler for pointing this out.

So, making pointer arguments effectively using alias-set zero for alias and
call clobbering computation would fix this.

[Bug c++/28858] New: [4.0/4.1/4.2 regression] Algorithm to find the end of a template parameter list is flawed

2006-08-26 Thread reichelt at gcc dot gnu dot org
If an error occurs in a template parameter list, the frontend
sometimes calls cp_parser_skip_until_found to find the ">" that
marks the end of the list. The algorithm used there has some flaws,
though:

1) It doesn't keep track of the nesting levels of "< ... >".
   This results in bogus error messages when templates are used as default
   parameters or when template template parameters are involved, e.g.:

 template class> struct A {};

   yields:

 bug.cc:1: error: 'TEMPLATE' has not been declared
 bug.cc:1: error: expected `>' before '<' token
 bug.cc:1: error: expected identifier before '>' token
 bug.cc:1: error: expected unqualified-id before '>' token

2) It doesn't stop at ";", or "{", or "}".
   (These tokens probably indicate the end of a declaration or the start of
   a function/struct body which is not part of a template parameter list.)
   Because of this large parts of the source might be skipped,
   if one forgets the closing ">", again resulting in bogus errors, e.g.:

 template 0;
 int j = i;

   yields:

 bug.cc:1: error: expected `>' before 'struct'
 bug.cc:2: error: expected unqualified-id before numeric constant
 bug.cc:3: error: 'i' was not declared in this scope

Posting a patch soon.

http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_04.html

"All functions not in the above table are considered to be unsafe with
respect to signals. In the presence of signals, all functions defined by this
volume of IEEE Std 1003.1-2001 shall behave as defined when called from or
interrupted by a signal-catching function, with a single exception: when a
signal interrupts an unsafe function and the signal-catching function calls an
unsafe function, the behavior is undefined."

malloc is not included in this list.

Now, it is unfortunate that glibc raises SIGABRT from inside malloc.

[Bug c/28862] New: attribute ((aligned)) ignored on vector variables

2006-08-26 Thread uweigand at gcc dot gnu dot org
The following test case

__attribute__ ((vector_size (16))) unsigned int foo[128/16]
__attribute__((aligned (128)));

[ and analagously

vector unsigned int foo[128/16] __attribute__((aligned (128)));

on ppc (where "vector" is defined to __attribute__((altivec(vector__)))
or spu (where "vector" is defined to __attribute__((spu_vector))) ]

compiles to

.comm   foo,128,16

Note that the user-specified alignment is ignored, and the default
alignment of 16 for this vector type is used instead.

The reason appears to be a problem in decl_attributes (attribs.c).
For this declaration, first the "aligned" attribute is processed,
and sets DECL_ALIGN to 128 bytes, as well as the DECL_USER_ALIGN
flag.  However, subsequently the "vector_size" attribute is
processed, and this this is marked as "type_required", the following
piece of code in decl_attributes:

  /* Layout the decl in case anything changed.  */
  if (spec->type_required && DECL_P (*node)
  && (TREE_CODE (*node) == VAR_DECL
  || TREE_CODE (*node) == PARM_DECL
  || TREE_CODE (*node) == RESULT_DECL))
relayout_decl (*node);

thinks it needs to recompute the decl properties.  In particular,

void
relayout_decl (tree decl)
{
  DECL_SIZE (decl) = DECL_SIZE_UNIT (decl) = 0;
  DECL_MODE (decl) = VOIDmode;
  DECL_ALIGN (decl) = 0;
  SET_DECL_RTL (decl, 0);

  layout_decl (decl, 0);
}

relayout_decl resets DECL_ALIGN without consideration of the
DECL_USER_ALIGN flag, and layout_decl then fills back in the
default alignment for the vector type.

The problem does not occur in 3.4, since decl_attributes there
works like this:

  /* Layout the decl in case anything changed.  */
  if (spec->type_required && DECL_P (*node)
  && (TREE_CODE (*node) == VAR_DECL
  || TREE_CODE (*node) == PARM_DECL
  || TREE_CODE (*node) == RESULT_DECL))
{
  /* Force a recalculation of mode and size.  */
  DECL_MODE (*node) = VOIDmode;
  DECL_SIZE (*node) = 0;
  if (!DECL_USER_ALIGN (*node))
DECL_ALIGN (*node) = 0;

  layout_decl (*node, 0);
}

and specifically keeps user-requested alignments.


Now, I'm not quite sure what the correct fix for 4.0 and mainline is.
Should be not call relayout_decl (as in 3.4)?  Or should we add the
DECL_USER_ALIGN check to relayout_decl (what about other callers of
this function)?

Richard, it appears you added both the DECL_USER_ALIGN check in
3.4, and the relayout_decl call in 4.0, see PR 18282.  Any opinion?

This works for me with "4.2.0 20060823" and "4.1.2 20060814" on
"i686-pc-linux-gnu".

Yes, if you change it so *everything passed to calls* is assumed to be
aliasing every variable with it's address taken, you will get the right
result in this case.

So what do you think will happen when you add one level of indirection
to the mess, and TBAA now prunes out *that* alias instead, so you miss
it again? (IE break the chain of clobber transitivity one link in the
other direcftion).

IMHO, i'd rather just see this bug, which has been in our compiler for 3
releases now, fixed properly in the next one, than hacked around.

It's relatively easy to fix this testcase in some hacky way, but i'm not
sure why we'd want to, when we know it will only fix this testcase, and
not the underlying problem.

I have a patch to fix this but I am not going to submit it until after 4.2
branches and my copyright assignment gets fixed as I wrote the patch for work.

[Bug c++/28774] Request for warning where const/volatile is ignored in a cast

HUH? Why do you want that?  GCC warns in more places than ICC will ever warn. 
To me this is an useless warning and in fact goes against what is questionable
even to a standards guy.

I am the reporter of this bug (with a new email-adress)
This problem seems to be solved with 4.1.1 =)

(Consider only #5 and forward - the first is wrong/irrelevant)

[Bug c++/28774] Request for warning where const/volatile is ignored in a cast

2006-08-26 Thread ian at airs dot com


--- Comment #4 from ian at airs dot com  2006-08-27 06:44 ---
I disagree.  It is always useful to optionally warn about meaningless code.  It
can be a way to find a real bug in the program.  It is not conceptually
different from existing warnings like -Wredundant-decls.  The code works fine,
but something is odd.

The behaviour of icc is irrelevant here.  If you want to close this again,
please give a reason why we should not warn about meaningless code.
